3. Installation Guide
Proper installation is crucial for optimal performance and longevity of your Pyramid WX65X woofer. If you are unsure about any steps, it is recommended to seek professional assistance.
3.1 Safety Precautions
- Disconnect the vehicle's battery before starting any electrical work.
- Wear appropriate safety gear, including eye protection.
- Ensure all wiring is correctly insulated and secured to prevent short circuits.
- Verify the speaker's impedance (4 Ohm) matches your amplifier's capabilities.
3.2 Mounting the Woofer
- Choose a Location: Select a suitable mounting location in your vehicle, typically a speaker enclosure or door panel, that accommodates the woofer's dimensions. The mounting depth required is 2.76 inches (70.1 mm).
- Prepare the Opening: If replacing an existing speaker, remove the old unit. If creating a new opening, carefully mark and cut a circular hole with a diameter appropriate for a 6.5-inch speaker. Ensure the mounting hole diameter is approximately 5.15 inches (131 mm).
- Position the Woofer: Place the woofer into the prepared opening, aligning the mounting holes on the speaker frame with the corresponding holes in the mounting surface.
- Secure the Woofer: Use the provided mounting screws to firmly attach the woofer to the mounting surface. Do not overtighten the screws, as this can damage the speaker frame.

3.3 Wiring the Woofer
- Identify Terminals: Locate the positive (+) and negative (-) terminals on the back of the woofer.
- Connect Wiring: Connect the positive wire from your amplifier to the woofer's positive terminal and the negative wire to the woofer's negative terminal. Ensure a secure connection.
- Insulate Connections: Use heat shrink tubing or electrical tape to insulate all exposed wire connections to prevent short circuits.

4. Operating Instructions
Once installed, follow these guidelines for optimal operation of your Pyramid WX65X woofer:
- Initial Power-Up: After installation, reconnect the vehicle's battery. Turn on your car audio system at a low volume to confirm proper functionality.
- Break-in Period: Allow a break-in period of approximately 10-20 hours of normal listening at moderate volumes. This allows the speaker's suspension to loosen and achieve its full performance potential.
- Volume Control: Avoid operating the woofer at excessively high volumes for prolonged periods, as this can lead to overheating and damage.
- Amplifier Settings: Adjust your amplifier's gain, crossover, and bass boost settings carefully to match the woofer's specifications and your listening preferences. Incorrect settings can cause distortion or damage.

- Cleaning: Periodically wipe the speaker cone and surround with a soft, dry cloth to remove dust and debris. Avoid using harsh chemicals or abrasive cleaners.
- Inspection: Regularly inspect the speaker for any signs of damage, such as tears in the cone or surround, or loose connections. Address any issues promptly.
- Environmental Protection: Protect the speaker from extreme temperatures, direct sunlight, and moisture, which can degrade materials over time.
